Anthracnose caused by Colletotrichum graminicola (Ces.) Wils is among the most aggressive maize diseases worldwide, considerably hindering crop productivity. To investigate the responses underlying the host-pathogen interaction involved in anthracnose infection, we conducted two feld experiments in some of the main grain producing areas of the State of Tocantins, in Brazil. Four maize hybrids (with diferential tolerance to C. graminicola) were sown in February and March, 2017. Chlorophyll fuorescence measures were performed according to the OJIP protocol; additionally, SPAD readings were conducted and productivity components were assessed. Inoculation with the fungus spore suspension afected the response curve of the chlorophyll fuorescence transient, SPAD index, and productivity components. Anthracnose stalk rot caused 20-25% reduction in grain weight, 6?8% reduction in maize ear size, and 20-23% reduction in ear weight. Furthermore, plants experiencing C. graminicola rot showed reduced SPAD index and a 24-34% reduction in the activity indicator of PSII (PITotal). These changes in the photosynthetic apparatus were successfully observed via chlorophyll fuorescence measurements. |

Due to massive energetic investments in woody support structures, trees are subject to unique physiological, mechanical, and ecological pressures not experienced by herbaceous plants. Despite a wealth of studies exploring trait relationships across the entire plant kingdom, the dominant traits underpinning these unique aspects of tree form and function remain unclear. Here, by considering 18 functional traits, encompassing leaf, seed, bark, wood, crown, and root characteristics, we quantify the multidimensional relationships in tree trait expression. We? nd that nearly half of trait variation is captured by two axes: one re? ecting leaf economics, the other re? ecting tree size and competition for light. Yet these orthogonal axes reveal strong environmental convergence, exhibiting correlated responses to temperature, moisture, and elevation. By subsequently exploring multidimensional trait relationships, we show that the full dimensionality of trait space is captured by eight distinct clusters, each re? ecting a unique aspect of tree form and function. Collectively, this work identi? es a core set of traits needed to quantify global patterns in functional biodiversity, and it contributes to our fundamental understanding of the functioning of forests worldwide. |
